Answer:
Per mile Chau takes 5.8 minutes per mile.
Step-by-step explanation:
To find this answer you would have to do the amount of time divided by the amount of miles. Always remember when dividing time most of the time goes first unless the problem / instructions say differently. So, when you do 50 divided by 10 you will get 5.8. So, Chau takes 5.8 minutes per mile.

i need help on question 4 A. Can someone please show working out too so I can understand it, thank you!
Answer:
[tex]Q=(9,11)[/tex]
Step-by-step explanation:
Solving (4a)
[tex]P (x_1,y_1) = (1,1)[/tex]
[tex]M (x,y) = (5,6)[/tex]
Required
Determine [tex]Q(x_2,y_2)[/tex]
To do this, we make use of the mid-point formula:
[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Substitute values for x, y, x1 and y1
[tex](5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2})[/tex]
Multiply through by 2
[tex]2 * (5,6) = (\frac{1+x_2}{2},\frac{1+y_2}{2}) * 2[/tex]
[tex](10,12) = (1+x_2,1+y_2)[/tex]
By comparison:
[tex]10 = 1 + x_2[/tex]
[tex]x_2 = 10 - 1[/tex]
[tex]x_2 = 9[/tex]
[tex]12 = 1 + y_2[/tex]
[tex]y_2 = 12 - 1[/tex]
[tex]y_2 = 11[/tex]
Hence, the coordinates of Q is (9,11)

WHAT IS THE EQUATION OF THE LINES IN SLOPE -INTERCEPT FORM ?
Answer:
y = 1x - 40
Step-by-step explanation:
Find the slope first which is the rise/run. And then you get the slope which is 1, and the slope intercept form is y = mx + b. Your y intercept is -40 so when you plug them in it makes y = 1x - 40

A rod of aluminium has a mass of 575.4g and a volume of 210cm3
Answer:
0.274g/cm^3
Step-by-step explanation:
density = mass / volume
so d = 575.4 / 210
d = 0.274g/cm^3

The formula for the volume, V, of a cone having the radius, r, and the height, h, is shown below.
V = 3r2h
Write the formula to calculate the height, h.
Answer:
V/3r²
Step-by-step explanation:
We are to make h the subject of the formula as shown;
V = 3r²h
Divide both sides by 3r²
V/3r² = 3r²h/3r²
V/3r² = h
Rearrange
h = V/3r²
Hence the formula to calculate the height h is V/3r²
Answer:
h = V/3r²

Figure A is a scale image of Figure B. Figure B Figure A What is the value of x?
Answer:
5.4
Step-by-step explanation:
Calculate value of x using similarity ratio
7.2/x = 4/3 cross multiply expressions
21.6 = 4x divide both sides by 4
5.4 = x
Answer:
5.4
Step-by-step explanation:
Solve for x: 3500=700*2^8x Check all that apply.
3500=700 \times 2 ^ { 8x }
\frac{3500}{700}=2^{8x}
5=2^{8x}
2^{8x}=5
\log(2^{8x})=\log(5)
8x\log(2)=\log(5)
8x=\frac{\log(5)}{\log(2)}
8x=\log_{2}\left(5\right)
x=\frac{\log_{2}\left(5\right)}{8}
[tex]\text{The \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)} \text{\ for the \textbf{equation},}\ 3500=700\times 2^{8x}.[/tex]
So, option c) and d) are correct.
Logs with base a, they are called Common Logs and Logs with base e are called Natural Logs.
[tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]
Given equation:
[tex]3500=700\times 2^{8x}\\[/tex]
In order to solve it for x first take logarithm both sides of the equation as follows:
We can take log natural as well as common log
1. taking common log:
[tex]log(3500)=log(700\times 2^{8x})\\log(3500)=log(700)+log( 2^{8x})\\log(3500)-log(700)=8x\ log( 2)\\\\log\dfrac{3500}{700}=8x\ log( 2)\\\\log5=8x\ log2[/tex]
Evaluating x as follows:
[tex]x=\dfrac{\log(5)}{8\log(2)}[/tex]
2. Similarly on taking natural log:
[tex]x=\dfrac{\ln(5)}{8\ln(2)}[/tex]
[tex]\text{Thus, the \textbf{value} of x is\ } \dfrac{\log(5)}{8\og(2)} \ \text{and} \dfrac{\ln(5)}{8\ln(2)}[/tex][tex]\text {Thus,x=\dfrac{\log(5)}{8\log(2)} and}[/tex]
So, option c) and d) are correct.
